内蒙古河套灌区小麦地复栽紫花苜蓿试验

Growing alfalfa in the stubble ground of wheat in the Hetao irrigation area of Inner Mongolia

小麦是内蒙古河套灌区主要的粮食作物 ,在 7月下旬收获后 ,还有约 2个月的作物生长期 ,为充分利用这段时间的光热资源 ,进行了小麦茬地复栽紫花苜蓿Medicagosativa的试验研究。试验证明 ,对紫花苜蓿提前育苗 ,适时移栽 ,可起到粮草双收的增产效果 ,经济效益和生态效益远高于传统复种的蔓菁Brassicarapa。

Wheat is the main grain crop in the Hetao irrigation area of Inner Mongolia. After harvesting at the end of July there is still about two months of crop growing season. In order to make the most of this period's light and heat resources, an experiment into planting alfalfa in the wheat stubble ground was carried out. The experiment proved raising alfalfa seedlings in advance and timely transplanting can result in an increasing-production double harvest of grain and forage, and that the economic and ecological benefit is much greater than growing the traditional second crop of Brassica rapa.
